I don't have experience specifically migrating websphere apps to jboss, but I do have extensive experience with both websphere and jboss portal. The first place to start with this kind of task is to ensure you're not using any vendor proprietary APIs (IBM in this case). You'll want to use the relevant portlet specification-defined APIs for your environment. I'm assuming your either migrating: - from websphere portal 6.0.X or earlier to jboss portal 2.6.X - from websphere portal 6.0.X to jboss portal 2.7.X Assuming you wouldn't be migrating off websphere 6.1 or 7, because they're both fairly new, so - you'll want to make sure you're migrating only JSR168-specific code to jboss. It may help if you: - describe your environment(s) in detail - PortletContext (in neither JSR168 nor JSR286) have a getService method - can you explain more about what API you're using here? - explain what you mean by "get the delegating methods" Hope this is helpful.
